DETAILED DESCRIPTION OF THE INVENTION

As shown in FIG. 1 and FIG. 2, a foldable chair with an awning bracketcomprises a foldable chair 1 and a foldable awning 2, which can achievelinkage folding. The foldable awning 2 comprises a soft awning 21 and anawning bracket 22. The said awning bracket 22 has a correspondingfoldable bracket 3 on either side, which comprises a supporting rod 31,a cross rod 32, a fixed seat 33, a connecting piece 34 and a foldableassembly 35. The supporting rod 31 is movably hinged on a fixed seat 33with a rivet 4, is fixed on the upper end of the backrest rod 11 of thefoldable chair with the help of the fixed seat 33, forms the linkagebetween the awning bracket 33 and the foldable chair 1, and composes afoldable assembly; the cross rod is used to unfold the soft awning 21.

According to FIGS. 2-5, a lower end of the supporting rod 31 in theawning bracket 22 is fixed on the upper end of the backrest rod 11 withthe help of the fixed seat 33. The fixed seat 33 is provided with ablocking component 331 limiting the forward swing of the supporting rod31, which is kept vertically with the help of the blocking component331, and the remaining is the folding component provided for freebackward swing of the supporting rod 31. The upper end of the supportingrod 31 is fixed with a connecting piece 34, on top of which, a circulararc groove 341 is provided. The cross rod 32 is movably hinged on theconnecting piece 34 with a rivet 4, and the folded cross rod 32 can besupported by local setup in the said circular arc groove 341, so as tomaintain the angle of the folded cross rod 32.

As shown in FIG. 3 and FIG. 5, a direction guide piece 36 is fixed onthe hinge component of the supporting rod 31 and fixed seat 33, and thethickness of the direction guide piece 36 is equivalent to the diameterof the supporting rod 31. The rivet 4 successively passes through thefixed seat 33 and direction guide piece 36, and forms the movable hingestructure. Furthermore, the rivet 4 passes through the center of thedirection guide piece 36, on the edge of which, the supporting rod 31 isfixed, so that the supporting rod 31 has an offset when it is unfoldedor folded in place, so as to satisfy the requirement of moving theawning bracket 22 to the back of the backrest rod 11 of the foldablechair when the awning is folded or not used.

As shown in FIG. 3 and FIG. 4, a direction guide piece 36 is also fixedon the hinge component of the cross rod 32 and connecting piece 34, andthickness of the direction guide piece 36 is equivalent to the diameterof the cross rod 32; the rivet 4 successively passes through theconducting piece 34 and direction guide piece 36, and forms the movablehinge structure. Furthermore, the rivet 4 passes through the center ofthe direction guide piece 36, on the edge of which, the cross rod 32 isfixed.

As shown in FIG. 2 and FIG. 6, a foldable assembly 35 is connectedbetween the foldable brackets 3 on both sides is composed of two longrigid pieces 351, one end of which is movably hinged with a rivet, andat the end of this hinge point 352, one side edge of at least one longrigid piece is bent to limit the excessively unfolded edgefold 353 ofanother long rigid piece 351; the other end of both long rigid pieces351 is respectively movably hinged on the vertical surface 342 of theconnecting piece 34 through a rivet, and forms an linkage structurebetween the foldable brackets 3 on both sides. In the unfolding process,the connecting piece 34 gradually travels to the highest point with thesupporting rod 31, and its vertical surface 342 faces forward, as shownin FIG. 2. Both long rigid pieces 351 are naturally unfolded under theirown gravity, and are hung down. Here, the edgefold 353 can present thelong rigid pieces 351 from being excessively unfolded, and can stablysupport the foldable brackets 3 on both sides and improve their windresistance. During the folding process, it is only necessary to turn thesupporting rod 31 or cross rod 32 towards the back of the backrest 11.When the supporting rod 31 is hung upside down, the connecting piece 34is also hung upside down accordingly, as shown in FIG. 6. Both longrigid pieces 351 are also naturally hung down under their own gravity,and the edgefold 353 under this angle loses the effect of limitinganother long rigid piece 351. Both cross rods 32 are automaticallyturned and hung down behind the backrest rod 11. Here, the foldablechair 1 relieves the awning effect of the foldable awning 2. When thefoldable chair 1 is folded again, both backrest rods 11 are gatheredtogether under an external force, driving the supporting rod 31 andconnecting piece 34 to be gathered together. Here, the edgefold 353loses the effect of limiting the long rigid pieces 351, which can beflexibly folded accordingly under their own weight.

In the above unfolding and folding process, it is only necessary tooperate the foldable awning 2 on one side due to the linkage effect ofthe foldable assembly 35 and the effect of the direction guide piece 36,which can maintain the angle consistency of the foldable brackets 3 onboth sides in the unfolding and folding process to the maximum extent.That is, if the backrest rod 11 is regarded as fixed, then the angle ofboth fixed seats 33 is consistent, so that the direction guide pieces 36fixed on both supporting rods 31 can still keep consistent directioneven if they are not synchronous in the unfolding or folding process,and will not be blocked due to torsion, thereby allowing for smootheroperation. Likewise, the direction guide pieces 36 fixed on the crossrods 32 have the same effect.

According to FIG. 6, the folded awning bracket 22 is gathered on theback of the backrest rod 11, occupies a little space, and is harmoniouswith the whole foldable chair.

According to FIG. 7, the foldable assembly 35 may also be arrangedbetween both cross rods 32, and is also composed of two long rigidpieces 351, one end of which is movably hinged with a rivet, and at theend of this hinge point 352, one side edge of at least one long rigidpiece 351 is bent to limit the excessively unfolded edgefold 353 ofanother long rigid piece 351; the other end of both long rigid pieces351 is respectively movably hinged on the cross rods 32 through a rivet,forms the linkage structure between the foldable brackets 3 on bothsides and can maintain the rigidity and strength of both cross rods 32.
